Having captured the DHCP conversations, neither device is asking for any
other than the standard options. 12, 13 , 23 and 24 and the reply is also
pretty much standard.

The HP devices are setting the lease preferred lifetime to 16secs, which
is a bit daft. But do accept the 72 hours I am providing, or at least
appear to.

I have tried reducing this to 24hrs but for some strange reason, the
daemon then crashes after a few minutes :-( Haven't been able to determine
why.

We have *LOTS* of HP MFDs, I find it strange that only a few a exhibiting
this 'unsociable' behavior :-)
